The present invention relates to a camp chair and has for its primeobject'to provide structure which is simple, foldable, easy tofmanipulate, inexpensive to manufacture,

= strong and durable, thoroughly efficient and reliable in 'use and otherwise well adapted to the purpose for which it is -designed.---

l/Vith the above and numerous other'object's in view as will appear as the c'le's'cription'p'roceeds, the invention resides incertain novel features of construction, and' in' the combination and arrangement of partsas will'be hereinafter more fully described'and claimed.

V In the drawings Figure 1 is a side elevation of a chairem- :bo'dyin-gthe features ofmy invention. V Figure 2'is'a front elevation thereof. Figure 3 is a horizontal section therethrough taken substantially on the line' '3-3 of Figure 2; S e

Figure 4 is a perspectiveview of the chair folded: 1

Figure 5 is a detailsection'taken substantially on the line 55'of Figure 2.

Figure 6 is a detail section showing the means for pivoting an arm to one of the back posts.

Figure 7 is a perspective view showing the pivotal connection between a pair of brace sections.

Figure 8 is a detail perspectiveview showing a portion of one of the posts and adjacent portions of braces associated therewith, and

Figure 9 is a fragmentary top plan View showing the rear portion of the seat.

Figure 10 is a fragmentary elevational View of a slightly modified form of the invention.

' Referring to the drawings in detail itwill be seen that numerals 5 denote front legs and numerals 6 rear legs. These legs 5 and 6 are of angular construction as isclearly indicated in Figures 3 and 8. The legs 6 extend higher than the legs 5 as is indicated to' advantage in Figure 1. Acrossthe upper portions of the legs 6 1s a back 7 formed of canvas or other suitable sheet flexible material.

has a pair of slots 8 one at each side thereof. Pairs of braces 9 are provided at all sides above the slots 8 there are provided brackets The posts 5 and 6 are slotted at their upper portions below the back 7 Each post of the chair. The braces of each pair "are pivoted together intermediate their ends as 'at 10 and the lower ends are pivoted as at 11 to the lower ends of the legs and the upper ends of the braces have pins 12 extending 55 throllgh the slots '8 and' 'slidab'le therein.

l/Vhe'n the legs are in "the extended position shown in "Figuresl and 2; it'will be noted that the pins 12 are at the lowerends of Y the slots '8 but when the 'legs are folded in 00 abutting relationship as shown injFigure 4;, the pins l2gare at the upper ends of the slots 8. The legs are held in the extended posi tion by braces which include sections 14 and 15 pivoted to the front and rear legsas at 16 65 and pivoted togeth'eras at 17 at'adjacent end portions, one ofthe endportions being ex tended and provided with' an' offset lug 19 to seat in a'iiotch 20 and prevent the pivot 1T from breaking downwardly but permitting 'the 's'ame'tobreak upwardly. I p A seat comprises a pair of angle iron side bars 25, the vertical flanges of which are extended to form tongues which are adapted to. pass through the front slots of the legs 5 and the rear slots of the legs 6 and a strip of canvas or like sheet material 26 is riveted or otherwise secured to the horizontal flanges of said bars 25; The rod 27 is pivoted as at 28 to the rear end of the horizontal flange of one of the bars25' so that it may be positioned as shown in full lines in Figure 9 to prevent the collapsing'ofthe seat or to the dotted line position shown in Figure 9 to permit the folding of the seat and allow the seat 26 to be rolled about the side bars 25. Thus by tilting the side bars 25 their tongues 25 may pass through the front and rear slots of the legs 5 and 6, after which the bars are straightened so that they will assume the position shown in Figure 1.. The rod 27 when in the position shown in Figure 9 will hold the side bars 25 spaced apart.

On theback posts or legs 6 immediately 40 between which and the posts arepivoted arms 30 as indicated at 31. The ends of these arms are adapted to rest on the upper ends of the legs 5 and to be held in place by slidable bolts 32 engaging under the uppermost in.

elements 35 provided on the back posts or legs 6.

Each keeper 35 is formed from a single length of spring metal anchored at one .end as at 36 to a post 6 and is flexed outwardly from the post and adjacent its free end bent about itself to provide a substantially U- shaped keeper notch 37 receiving therein the horizontal portion of an arm at the free end of the arm.

To free the arm 30 from the keeper the latter is swung inwardly or to the right in Figure 10 disengaging the free end of the arm from the notch 37 whereby the arm is free to swing about its pivot 34:.

It is thought that the construction, operation, utility and advantages of this-invention will now be quite apparent to those skilled in this art without a more detailed description thereof.

The present embodiment of the invention has been described in considerable detail merely for the purposes of exemplification since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description.

It will be apparent that changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

Having thus described my invention, what I claim as new is: e

A chair of the class described comprising 1 a pair of front legs and a pair of rear legs, each leg being of angle shape in cross section and the rear legs being longer than the front legs, each leg having an elongated slot in each flange thereof in an upper portion of the leg, a pair of braces connecting each leg to each of the adjacent legs, the braces of each pair being pivotally connected together interme;

brace connecting the rear legs together, a 7

pair of arms each of which haveone end T pivotally supported from a rear leg and latchv means for connecting the front endof each arm to a front leg. 5 f

In testimony whereofI aflix my signature.
